Key to species of genus Kakuna (male)

1. Anal segment of male with processes ( Figs 16, 17, 19 View FIGURES 12 – 22 ); two processes of diaphragm very long, separated basally ( Figs 19, 20 View FIGURES 12 – 22 ); aedeagus in profile straight, without any process ( Fig. 21 View FIGURES 12 – 22 ); genital style in profile with apex subquadrate, apical margin truncate ( Fig. 22 View FIGURES 12 – 22 ) ......................................................................................... K. nonspinata sp. nov.

- Anal segment of male without process ( Figs 5 View FIGURES 1 – 11 , 28, 30 View FIGURES 23 – 34 ); two processes of diaphragm relatively short, both touching at base or with a common stalk basally ( Figs 6 View FIGURES 1 – 11 , 31 View FIGURES 23 – 34 ); aedeagus in profile curving dorsally, apical half with spine-like processes ( Figs 8, 9 View FIGURES 1 – 11 , 32, 33 View FIGURES 23 – 34 ); genital style tapering apically ( Figs 10, 11 View FIGURES 1 – 11 , 34 View FIGURES 23 – 34 ) ............................................................ 2

2. Aedeagus with two rows teeth along apical half of lateral margin ( Figs 32, 33 View FIGURES 23 – 34 ); inner margin of genital style with a nipple-like process medially ( Figs 30, 34 View FIGURES 23 – 34 ) ............................................................................... K. zhongtuana sp. nov.

3. Ventral margin of anal segment produced ventrally; pygofer in profile with laterodorsal angle not produced caudad; processes of diaphragm short; aedeagus not expanded at apex, apical part with five pairs of spine-like processes laterally; genital styles relatively broad and short ........................................................................... K. yushaniae (Yang)

- Ventral margin of anal segment not produced ventrally ( Fig. 5 View FIGURES 1 – 11 ); pygofer in profile with laterodorsal angle strongly produced caudad ( Fig. 4 View FIGURES 1 – 11 ); processes of diaphragm long ( Fig. 6 View FIGURES 1 – 11 ); aedeagus in profile distinctly expanded at apex, apical part with six spine-like processes ( Fig. 8 View FIGURES 1 – 11 ); genital styles relatively slender and long ( Figs 5, 10, 11 View FIGURES 1 – 11 ) .................. 4

4. Processes of diaphragm straight; aedeagus with three spine-like processes both dorsally and ventrally; suspensorium with stalk longer in middle line than broad ......................................................................... K. kuwayamai Matsumura
